Permanent magnet generators

We offer three different topologies to cover all tidal and wave energy applications from 1 MW to 8 MW and higher: direct-driven, medium-speed and high-speed.

The Switch PMGs are available as stand-alone machines connected to the high speed shaft of the turbine. Additionally, we can design fully integrated direct drive or medium speed machines that can be a structural part of the application.

Cooling options are passive sea water surface cooling or a closed liquid cooling system. Each PMG topology is designed to best match specific wave or tidal conditions and applications. This guarantees virtually maintenance-free operation and the lowest cost of energy.
